正则表达式中以"/“开头的Jayway jsonpath

Question

当涉及到使用包含xpath的regex时，我遇到了jayway jsonpath的问题。下面是我的json：

{
  "status": "success",
  "resources": [
    {
      "id": "Attachment-20796b26-7a16-4a3d-b53c-b30d9f3cb798.TXT",
      "name": "1996032897__test1.CREDITPRINTFILE",
      "mimeType": "text/plain",
      "url": "https://test.com"
    }
  ]
}

下面是我的表达式: resources?(/__test1.CREDITPRINTFILE/.test(@.name))

我得到以下错误：

我也尝试在在线评估工具中使用相同的表达式：https://jsonpath.herokuapp.com/

Jayway -给出了相同的错误-预期路径节点Gatling，Nebhale - errors out Goessner -给出了有效的结果

我在用最新版本的jayway我想-

<dependency>
  <groupId>com.jayway.jsonpath</groupId>
  <artifactId>json-path</artifactId>
  <version>2.4.0</version>
</dependency>

问:如果jayway不能解决这些类型的表达式，有没有其他的java库可以用来解决这些问题？

假设您正在寻找“名称中包含__test1.CREDITPRINTFILE的资源”，jsonpath表达式resources[?(@.name =~ /.*__test1\.CREDITPRINTFILE/)]将适用于Jayway。在https://jsonpath.herokuapp.com/进行了测试
